| Abstract: |
| Reducing steam consumption can reduce the production cost of soybean oil crushing enterprises. Taking a 5 000 t/d soybean processing plant as an example, measures to reduce steam consumption were introduced in terms of technological transformation and refined management. Technical transformation measures included changing the steam jet pump of the original leaching line to a liquid ring vacuum pump, changing the layer disc stripper to a sieve-plate stripper, and changing the grid plate gap in the drain section of the extractor from 0.4 mm to 1.2 mm, and recycling the spent gas discharged from the first layer of the DC evaporator, the secondary steam discharged from the stripper and the heat of the steam condensate. Refined management measures included strengthening refined control of equipment, perfecting necessary measuring equipment, strengthening staff operation control level and KPI performance appraisal management. Through the above measures, about 45 kg/t of steam (based on raw materials) could be saved. |
